Advanced Imaging of Elementary Circuits

Students commonly find the second semester of introductory physics to be more challenging than the first, probably due to the mechanical intuition we acquire just by moving around. For most students, there is no similar comfort with electricity or magnetism. In an effort to combat this confusion, we decided to examine simple electric circuits with either a high-speed camera or a thermal imager in an effort to make things like current and voltage as familiar as slow motion or temperature.
